| titleOfInvention | Method for producing acyl-substituted aromatic compound |
| abstract | (57) Abstract: A Friedel-Crafts catalyst is used in a conventional method for producing an acyl group-substituted aromatic ketone, but this catalyst generally requires a stoichiometric amount or more. There are many operational and environmental problems to be solved, such as the generation of a large amount of wastes such as hydrochloric acid due to hydrolysis during the isolation of lactic acid. In addition, in the acylation reaction using zeolite which is considered as an alternative method, There is a problem in industrialization because the catalyst activity is low and it decreases over time. An aromatic compound and a carboxylic acid or a derivative thereof are reacted by contacting with a catalyst containing zeolite in the presence of hydrogen. |
